GiD forum

Hello,

which version of GiD are you using?
have you tried the last 6.3.0b version or
the new 7.0beta2, located at
ftp://gid.cimne.upc.es/pub/gid_adds/Windows ?

With the 7.0beta2 version you will get the enclosed
pictures.
Note that in the last zoomed one element the gauss points
are concentrated at one side of the element.
I don't know if this is what you want, but
to distribute the gauss points along the whole hexahedral
elements, the natural coordinates should be between
-1.0 and 1.0. For tetrahedral elements should be between 0.0 and 1.0.

Subject: [GiDlist] Contour fill and contour lines
Date: Sat, 15 Jun 2002 04:04:42 -0500

I can't see contour fill and contour lines from results located
OnGaussPoints of hexahedra elements.

The problem is only whit the results located OnGaussPoints, the results
located OnNodes works fine:


My displazaments are located on nodes without problems





My stress are located on Gauss points an I only can see the boundary and
the results table:





Anybody can help me, I attach a rar file with the mesh and results.

Advanced thanks

Hello,

Thanks for your help last time. Here I have three more questions.

First, is there a way to know the neighboring nodes around one specified node? I know how to get them by
some visual tools. However, I need neighboring node numbers listed for every node in the ouput file. In
other words, except node coordinates, element connectivities, material and conditions in my output file I
want to get adjacent node numbers for each node. Is it possible to do that?

Second, is there a way to assign element size for a specified volume? In the manual there are some
instructions to show how to assign element size around a point, a line and a surface, but no volume. I saw a
drop-down menu in the software to assign element size to a volume. However, it did not work when I tried.

Lastly, how do I generate a mesh if I have an internal boundary, such as a stright line (not even a crack,
no void) in a 2D elastic body? It doesn't intersect with any boundaries. Can I generate a mesh for such a
case?

Sorry these are too much. Thanks in advance.

I have been using the 6.1.5 version and now I´m trying with the 6.3.0b but I
can't see my results in Contour Lines format.

When I ask GiD for Countour Lines, either only the boundaries and the
results table are shown or the program crashes! I'm very interested in
countour lines in order to see the strees bulb in soils.

So, my question is the next: Is there any way to see Contour Lines
OnGaussPoints?

About your comments of the distribution of gauss points, you were right, I
had an erroneous distribution.

Tanks again!

Alejo J.

1- Is not available from GiD the list of neighboring nodes of another node,
this information must be reconstructed
outside GiD. Must create a external program in any language to read the
mesh and re-write this list of
edge-connected nodes.
This auxiliary program can be invoked automatically from the bat file
pressing the "calculate" menu.
2- You can assign a uniform size to a volume (the volumes are drawn in cyan
color). If the boundary requires a small
size, then the element sizes it will grow gradually (according to the
transition parameter) until trying to reach the
size prescribed in the volume.
To assign a non-uniform size to the volume interior must be used a
"background mesh" file: a file with a covering
mesh and desired approximate size specified in the nodes or elements.
3- The surface must be dividided using this internal boundary: create
aditional lines to connect with the boundary and use
"Geometry-Edit-Divide-Surfaces-Split" to break the original surface.

no, you are right, by now, contour lines for gauss points
results over hexahedrals can not be done, nor even with version 7;
but for triangles and quadrilateral works.
